Question

Topic: Singly Linked List
Implement the following functions in C++ program. Read the question carefully.  (See attached photo for reference) 

 

  • void isEmpty()

This method will return true if the linked list is empty, otherwise return false.

  • void clear()

This method will empty your linked list. Effectively, this should and already has been called in your destructor (i.e., the ~LinkedList() method) so that it will deallocate the nodes created first before deallocating the linked list itself.

 

 

public: LinkedList() { index = 0; head = NULL; tail = NULL; -LinkedList() { clear();
Transcribed Image Text:public: LinkedList() { index = 0; head = NULL; tail = NULL; -LinkedList() { clear();
class LinkedList : public List { node* head; node* tail; int index; node* create_node(int num) { node* n = (node *) malloc( sizeof(node) ); n->element = num; n->next = NULL; return n; }
Transcribed Image Text:class LinkedList : public List { node* head; node* tail; int index; node* create_node(int num) { node* n = (node *) malloc( sizeof(node) ); n->element = num; n->next = NULL; return n; }
